Roots and liquid ring vacuum system in the application of ABS and PS

ABS resin is a kind of between general plastics and high-performance engineering plastics thermoplastic engineering plastics, widely used in household appliances, IT industry, building materials, automobile industry and other categories. At present, the ABS production in the world only after polyethylene, PVC, and polypropylene and polystyrene, in fifth place.ABS project can use the DOW chemical company’s continuous bulk process and conventional emulsion polymerization process.This continuous ontology method compared with the conventional emulsion polymerization process, consumption process, short, cover an area of small, low investment, less pollution features, have very strong economy.

Polystyrene (PS) is one of the five common thermoplastic synthetic resin in the world.Because of good mechanical performance, transparency and water resistance, chemical resistance,Especially with excellent electrical insulation properties and low moisture absorption, easy processing, widely used in household appliances, electronic appliances, packaging, construction and consumer goods category.Chinese usually have many craft bag manufacture company, the vacuum system is the necessary products in the process of manufacture a complete set of packages.

In ABS and PS projects, All will need to use the roots vacuum pump and liquid ring vacuum pump unit .ABS project for the disposal of medium air + n2 + ethyl benzene, styrene and acrylonitrile.PS project disposal medium for air+ethyl benzene and styrene.Because of styrene and acrylonitrile and toxic basis country let the cat out of the amount of styrene environmental protection request, our company to the user to introduce liquid ring vacuum pumps with double end face mechanical seal and USES the API53 flushing.
